RenderScript is primarily oriented for use with data-parallel computation, although serial 74computationally intensive workloads can benefit as well. 75 76RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen 77in image processing. Intrinsics provide extremely high-performance implementations of standard 78functions with a minimal amount of code. 79 80This sample shows how to access and use the blur, convolve, and matrix intrinsics: 81 82```java 83mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS)); 84mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS, 85 Element.U8_4(mRS)); 86mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS, 87 Element.U8_4(mRS)); 88``` 89 90RenderScript intrinsics will usually be the fastest possible way for a developer to perform these 91operations. The Android team works closely with our partners to ensure that the intrinsics perform 92as fast as possible on their architectures — often far beyond anything that can be achieved in a 93general-purpose language. 94 95[1]: http://developer.android.com/guide/topics/renderscript/compute.html 96]]> 97 </intro> 98 </metadata> 99</sample> 100
